Before you install Zoweâ„¢, you must install IBM SDK for Node.js on the same z/OS server that hosts the Zowe Application Server. Review the information in this topic to obtain and install Node.js.

Supported Node.js versions#

The following Node.js versions are supported to run Zowe. See the Hardware and software prerequisites section for the prerequisites that are required by Zowe.

The corresponding IBM Knowledge Center for Node.js - z/OS lists all the prerequisites for Node.js. Some software packages, which might be listed as prerequisites there, are NOT required by Zowe. Specifically, you do NOT need to install Python, Make, Perl, or C/C++ runtime or compiler. If you can run node --version successfully, you have installed the prerequisites required by Zowe.

  • Node.js Version 6

    • z/OS V2R2 with PTF UI46658 or z/OS V2R3

  • Node.js Version 8

    • z/OS V2R2: PTFs UI62788, UI46658, UI62416 (APARs PH10606, PI79959, PH10740)

    • z/OS V2R3: PTFs UI61308, UI61376, and UI61747 (APARs PH07107, PH08353, and PH09543)

      Known issue: There is a known issue with node.js v8.16.1 and Zowe desktop encoding. See the GitHub issue for details.

      Workaround: Use node.js v8.16.2 or later, which is available at https://www.ibm.com/ca-en/marketplace/sdk-nodejs-compiler-zos. Download the pax.Z file.

  • Node.js Version 12

How to obtain IBM SDK for Node.js - z/OS#

You can obtain IBM SDK for Node.js - z/OS for free in one of the following ways:

  • Order the SMP/E edition through your IBM representative for production use
  • Use the PAX evaluation edition for non-production deployments

For more information, see the blog "How to obtain IBM SDK for Node.js - z/OS, at no charge".

Hardware and software prerequisites#

To install Node.js for Zowe, the following requirements must be met.

Hardware:

IBM zEnterprise® 196 (z196) or newer

Software:

  • z/OS UNIX System Services enabled
  • Integrated Cryptographic Service Facility (ICSF) configured and started on systems where Node.js is run.

Configuring ICSF#

This section summarizes the high-level steps that you can follow to configure and start ICSF. For more information, refer to ICSF System Programmer's Guide and ICSF Administrator's Guide.

  1. Add CSF.SCSFMOD0 to the LNKLST concatenation.

  2. APF authorize CSF.SCSFMOD0.

  3. Modify IKJTSOxx to add CSFDAUTH and CSFDPKDS in the AUTHPGM parameter list and in the AUTHTSF parameter list.

  4. Create the following ICSF Key Data Sets:

    • Cryptographic Key Data Set (CKDS)

      Sample JCL: SYS1.SAMPLIB(CSFCKDS)

    • Public Key Data Set (PKDS)

      Sample JCL: SYS1.SAMPLIB(CSFPKDS)

    • (Optional) If you want to have PKCS#11 support through ICSF, you should create Token Key Data Set (TKDS)

      Sample JCL: SYS1.SAMPLIB(CSFTKDS)

  5. Copy ICSF Installation Options sample (SYS1.SAMPLIB(CSFPRM00)) to the system PARMLIB data set, and change the name of the data set on the CKDSN and PKDSN statements to the name of data sets you created previously.

  6. Create ICSF startup procedure. Copy SYS1.SAMPLIB(CSF) to the system PROCLIB and change the data set name in the CSFPARM DD statement to the name of the installation options data set you provided previously.

  7. (Optional) Define a RACF Started Procedure profile for CSF procedure in CLASS(STARTED).

  8. Start ICSF (S CSF).

Note: You might need IPL before starting ICSF.

Installing the PAX edition of Node.js - z/OS#

Follow these steps to install the PAX edition of Node.js - z/OS to run Zowe.

  1. Download the pax.Z file to a z/OS machine.

  2. Extract the pax.Z file inside an installation directory of your choice. For example:

    pax -rf <path_to_pax.Z_file> -x pax

  3. Add the full path of your installation directory to your PATH environment variable:

    export PATH=<installation_directory>/bin/:$PATH

  4. Run the following command from the command line to verify the installation.

    node --version

    If Node.js is installed correctly, the version of Node.js is displayed.

  5. After you install Node.js, set the NODE_HOME environment variable to the directory where Node.js is installed. For example, NODE_HOME=/proj/mvd/node/installs/node-v6.14.4-os390-s390x.

Installing the SMP/E edition of Node.js - z/OS#

To install the SMP/E edition of Node.js, see the documentation for IBM SDK for Node.js - z/OS. Remember that the software packages Perl, Python, Make, or C/C++ runtime or compiler that the Node.js documentation might mention are NOT needed by Zowe.
